Abstract
A 61-year-old Japanese male developed acute abdomen after drinking too much and was admitted to our hospital. Severe acute pancreatitis was diagnosed. A month after this admission, he complained of abdominal pain and frequent vomiting . A plain abdominal film showed an ileus. On colonoscopy, an inflamatory stenosis was presented in the transverse colon that did not permit the scope to pass. The stenotic portion consisted of edematous, reddish mucosa without erosions or ulcer. Endoscopic balloon dilation (outer diameter 30mm, with the over the wire balloon used for treating achalasia) was done twice a 1-week interval between procedures. The stenosis improved without the need for surgery.
